The dork in me has to says you need one of the cast selections from Transformers up there.

Orson Welles as Unicron, Leonard Nimoy as play GalvatronRobert Stack as Ultra Magnusand Scatman Crothers actually played Jazz in the actual series as well as the movie!

Joking aside though, that's a pretty good list, there's some like Brent Spiner as Data that it's tough to make a call for whether or not their big screen appearences can be fully valued since so much of the character is established and created before the film debut. I'll try and toss up a more serious list of favorites when I'm at work tonight.

Well, as much as I hate to go the Otaku route here, I think my number one would have to be Motoko Kusanagi from Ghost in The Shell. I was thinking about how well that film really captures how blurry the definition of "humanity" gets when I was falling asleep.
